The invention discloses a digit array radar DAM reception digit circuit test system, comprising a power supply device, a test signal source, a clock source and a computer. The test signal source provides a signal to be detected to a reception digit circuit board to be detected. The improvement in the invention is that the digit array radar DAM reception digit circuit test system comprises a power divider, a test clamp, and an optical fiber adapter plate; the power divider performs power dividing on the signal to be detected and the signal to be divided is divided into signals of multiple paths which are provided to the test clamp; the power supply device and the clock source are connected to the test clamp; the test clamp supplies the test signal, the clock supplied by the clock source and the power supply supplied by the power supply device to the detected reception digital circuit board through a probe; the test clamp is controlled by the computer; and the optical fiber adapter plate is connected to the reception digit circuit board and the computer. The invention has advantages that the test system provided by the invention can detect the indexes of the signal-to-noise ratio, the noise coefficients, the channel isolation and interchannel amplitude consistency of the plurality of channels of the digital circuit in parallel, and greatly improves the test efficiency of the reception digital circuit.
Description
technical field [0001] The invention discloses a digital array radar DAM receiving digital circuit test system, which belongs to the radar receiver test system. Background technique [0002] Digital array radar has the characteristics of large dynamic range, easy realization of multi-beam, low loss, low sidelobe, strong anti-interference ability, high precision and high reliability, so it has been widely used. Digital array radar uses a receiver Digital Array Module (r-DAM) and a transmitter Digital Array Module (t-DAM) to implement digital beamforming technology. With the development of digital array radar technology, r-DAM is required to have higher performance indicators, so the accuracy and precision requirements for receiving digital circuit testing in r-DAM are also getting higher and higher. In order to obtain higher operational indicators for digital array radar, the main way is to increase the number of radar fronts, that is, to increase the number of r-DAM and the...
